Venus Shadow

The reflected light from Venus, with a magnitude of - 4.5 at its brightest, is sufficient to cast shadows. Venus shadows are fairly easy to discern in dark locations as is seen by the telescope's shadow cast on the wall by the light from Venus at a magnitude of - 4.3. Also, note the reflection of Venus on the tube-light as indicated by the arrow (click on photo to enlarge). The photo above was taken in southeastern France, at Breil-sur-Roya, on November 17, 2007, between 04:21 and 04:34 UTC -- before astronomical twilight began.
